How to convert .flv to .m4v files through FFmpeg

Question

I want to convert FLV files to M4V files. What is the exec (PHP) Linux code for this conversion?

Answer 1

In the most simple case:

ffmpeg -i input.flv -an -c:v copy output.m4v

This will copy the raw video stream, discard audio, and change the container.

Just wrap this in your PHP exec line as you need it. For example:

<? exec("ffmpeg -y -i $infile -an -c:v copy $outfile"); ?>

Don't forget to update FFmpeg to the latest version depending on your operating system. And, as @soandos mentioned, check out my blog post on that subject: FFmpeg: The ultimate Video and Audio Manipulation Tool - Super User Blog
